Hi guys, I really want to thank you all for your feedbacks which give me the will to always add cool features to Nautilus. Thanks to that, let me introduce the new stable version with some new features: - better groups (now the granularity is method and no longer class) - better algorithm for coloring protocols and methods - more menu entries and shortcuts - Monticello integration - OCompletion integration - a lot of new icons :) (and some cleans in the code but ^^) Thanks every one for your good energy :) Ben
